I booked this tour for a group of 4 via Viator and Ilimo tours was the company. The Guide had good information but he was not approachable. They did not have enough water bottles. Snacks were not provided. When I asked the Guide if you can make a stop near the Garden of Gods signboard, he said Sorry, I can't stop there and he asked to google and collect the pictures. I believe that is NOT the right way to answer. Also, at every stop, he was more concerned about taking pictures with his camera rather than giving information to us. The time given in few stops were not enough. After every stop, the guide didn't bother to take the headcount.
Not a good guide is all i can say.
